In the last 20 years, researchers have investigated solutions to enable seamless access to online resources within the context of electronic health record (EHR) systems. “Infobuttons” are among these solutions. Based on contextual attributes that describe the EHR user, the patient, and the care setting, infobuttons anticipate clinicians’ information needs and provide automated links to a set of relevant knowledge resources to assist clinical decision support.

WorldVistA EHR is an open source electronic health record (EHR) based on the highly acclaimed VistA system of the United States Department of Veterans Affairs (VA). The foundation for WorldVistA EHR was developed as part of the VistA-Office project, a collaborative effort funded by the Centers for Medicare & Medicaid Services (CMS), an agency of the Department of Health and Human Services (DHHS).
